' is extinguished.

1 A further object is to provide a device of the character'indicated inwhich the removal of the coin -receptacle'will operate to break theelectric circuit and'make thedevice inoperative. v j

The various novel features of the invention will appear in the detaileddescription taken in connection with the. accompanying drawing formingpart of this specification desk lamp and bank;

' of the coin receptacle, and

in which like reference characters indicate similar parts throughout.

Figure 1 is an elevation of the improved 1 Fig. 2 is a vertica same; i oa Fig. 3 is a planview of the funne'limouth 1 section through the Fig. 4is a fragmentary bottom viewillustrating means for securing the coinreceptacle in the lamp casing. a c

In the drawings there is indicated a stand having arelatively widehollow base 1 which is adapted to serve as a shell to contaln a coinreceptacle or bank 18. The base is pro- 'vi'ded with an uprightextension 2 within I indicate'the end walls ofa coin chute, the.

which the coin-controlled mechanism is located and 3 indicates a reducedportion at the top of the stand within which is mounted a socket 40f theordinary type for receiving electric bulb '5. The portion 2 above thebase. 1 isprovided with a slot 6 through which a coin may be insertedand 7 and 7 wall 7' bei-ngsomewhat lower than the wall 7 and serving asa backing for an electrical terminal 8 which is suitably insulated fromthe wall"? and also supported and suitably insulated from a shelf9 whichextends inwardly over the hollow base 1. This terminal 8 is connected toa spring contact 10 which is positioned below contact 30 con-,

nected with the end of wire 17.

Arranged opposite the terminal the other sideof the coin slot is anotherspring contact 11 comprising a spr ng finger wh1ch is suitably securedtoan insulating support- 12 and projects into the coin slot so as tointercept and support the coin which is in:-

serted thereimthecoin, whenheld between the terminals 8 and ll, servingas a conductor therebetween whereby electric current mayl'flow through aconductor 13 which-ex -c I f anna tends betweenlthefspring finger 11 andthe a socket 1. vThe spring finger- 211 is flconnected to a pull-cord14; by-a suitably insulated connection which cord extends through I anopening in the stand and serves, when drawn uponyto pull the free end'ofthe finger-terminal 11 out of the coin slot thus permitting the coin todrop into the coinreceptacle 18.

The return wire 15 which is insulated from i but supported "by thesocket 4; may pass di rectly out of the stand, but has been shown ascomprising two sections having a bind- 7 ing post 16 between thesections, and is ordinarily joined to the wire 17 forming a doule'twisted cord 31 as is usual. 7

The base 1 is constructed to receive a coin receptacle 18 being providedwith inwardly directed annular flanges 2627, the outermost flange 26being broken away at suitable points to. permit-the passage of outwardlydirected lugs 24 provided uponthe coin receptacle 18 which are adaptedto ,co-act with j said flange by rotation of the receptacleto securesame in position. The receptacle 18 is provided with a funnel shapedcoin guide 21 in its top, said funnel shaped guide being provided at itslower and smaller end with a cruci-form opening 22 to permit the passageof coinsdownwardly into the receptacle but adapted to prevent theiroutward passage therefrom. The receptacle'lS is fur ther provided uponits top with a suitable insulating ring 23'which is adapted to engagespring contact 10 upon'the insertion of the receptacle into base landforce sameagainst I contact member 30 to complete the circuit and putthe device. in condition for operation. A suitable slide door 19 isprovided for the receptacle whichm'ay be secured as by lock 20. Springmembers 28 provided adjacent the lower edge'of the receptacle areadapted to contact with the upper flange 27 of the base 1 to securethe'container inposition' and prevent movement thereof and suitablethumb pieces 32 may be provided upon its bottom tO-f2l0ll1t2lte itsIDSBFCIOIL and 're-: H

moval in the lamp.

I In operation it will be noted that with 1 coin receptacle 18 removedthe circuit to the lamp is broken between contacts'10 and 30 as well asbetween. contacts 11 and'8. The

placing of the coin receptacle within the suitable coin in slot 6operates to bridge contacts 11 and 8 thus completing the circuit to thelamp. 1 Vhen it is desired to extinguish c the light, pull-cord 14 isused by which sprin'g contact finger 11 can be'withdrawn from the coin:chute whereupon the coin drops through the funnel shaped guide 21 andthe cruci-form opening22 into the coin receptacle. flhe'release of thepull cord 1& then permits the return of contact'll into its "positiontorepeat the'pr'ocess.

' p What i claim 15::

In an electric larnp, a stendconiprising a the stand comprising a springfingerextend 1 ing into a coin chute and against" which a coin willrestto complete the circuit with the lampymeans exterior of the stand forpulling on the finger to allow the coinlto pass, a coin receptacleedaptedtofb'e secured within the hollow base of the stand; and Y vmeanswhereby the withdrawal of the coin V i receptacle will operate to-breakthe circuit. In testiinony whereof I afiix mysignature.
